It is often difficult to know exactly when make will expand the
variable, and usually it can only be expanded after the dependencies
have been built (e.g. pkg-config or the .pc file). Using a backtick
instead makes it very clear that it will be expanded only while
executing the command.
This change is useful for two cases:
1. The per-package staging (and host) directory will be created as part
of the configure step, so any $(shell ...) variable that is used in
the configure step will fail because the directory doesn't exist
yet.
2. 'make printvars' evaluates the variables it prints. It will therefore
trigger a lot of errors from missing .pc files and others. The
backticks, on the other hand, are not expanded, so with this change
the output of 'make printvars' becomes clean again.
This commit contains only the easy changes: replace $(shell ...) with
`...`, and also replace ' with " where needed. Follow-up commits will
tackle the more complicated cases that need additional explanation.
After this change, the following instances of $(shell ...) will remain:
- All assignments that use :=
- All variables that are used in make conditionals (which don't expand
the backticks).
- All variables that only refer to system executables and make
variables that don't change.
- The calls to check-host-* in dependencies.mk, because it is eval'ed.

This version comes with a new build system based on autoconf/automake,
so we switch from generic-package to autotools-package. However, since
the tarball does not contain a pre-generated configure script, we have
to set LOGROTATE_AUTORECONF = YES.
[Thomas:
- add comment explaining why AUTORECONF = YES is needed
- expand commit log
- use --without/--with instead of --with=yes/--with=no
- fix indentation in the ACL condition]

Without using the pkg-config the dependencies are not included for a
static linking so it fails to build.
These failures are fixed by linking the libintl library that is a
dependency of the popt library.
This commit to be useful requires the previous commit 'popt: add to the
"popt.pc" file the libintl library'.
Fixes:

Minimal defconfig to reproduce the build failure:
BR2_STATIC_LIBS=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_PACKAGE_GETTEXT=y
BR2_PACKAGE_LOGROTATE=y
[Thomas: fix commit log, since the library is named 'popt', not
'opt'.]

As discussed, users should use a rootfs overlay or a post-build script
instead of a custom skeleton to override files installed by Buildroot,
so there is no point in having conditions when installing init scripts
or configuration files.

Since the trailing slash is stripped from $($(PKG)_SITE) by pkg-generic.mk:
$(call DOWNLOAD,$($(PKG)_SITE:/=)/$($(PKG)_SOURCE))
so it is redundant.
This patch removes it from $(PKG)_SITE variable for BR consistency.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

Thanks to the pkgparentdir and pkgname functions, we can rewrite the
GENTARGETS macro in a way that avoids the need for each package to
repeat its name and the directory in which it is present.
